Peter Sutcliffe, the Yorkshire Ripper, was the most infamous and terrifying serial killer in Britain of the 20th century. Active as early as 1969, Sutcliffe was ultimately arrested for the murder of 13 women and attempting to murder a further 7 more. The Yorkshire Ripper attacks and the media circus surrounding his activity scarred the nation and lead to an enormous, desperate police operation to catch the killer, unlike any other in the history of Great Britain. It remains to this day among the most famous, controversial & significant manhunts ever undertaken in Britain.
